Abstract: A fluid/particle separator comprises an apertured rotor (17) substantially closing a circular chamber inlet to which a particle-containing fluid is fed in use. The rotor apertures (19) are bounded by surfaces (22), within the thickness of a rotor disc or on vanes (20) projecting towards the interior of the chamber, which surfaces are inclined to the axis of the rotor, face upstream of the fluid flow and face in the circumferential direction of motion of the rotor such that, in use, particles in the flow rebound from the rotor surfaces and cleansed fluid passes through the apertures and is centrifuged by the inclined surfaces. Baffles including a coaxial plate (13) and radial vanes (14) within the chamber guide the major fluid flow to an axial fluid outlet (5), while a small proportion of the flow is forced through a peripheral clearance (18) between the rotor and the housing (7) to prevent a flow of particle-containing fluid in the opposite direction. The separator apparatus may be mounted across an inlet to a motor, pump or impeller to prevent dust in the air from entering it, and particularly across the inlet to an impeller in a vacuum cleaner.

Abstract: In a transmission system of a class IV partial response code succession produced in accordance with a predetermined encoding rule, a transmitter intentionally violates the encoding rule to carry a subsidiary signal, so that an intentional violation appears in a receiver as two consecutive violation signals located in every other time slot, differing from an unintentional violation occurring during transmission. In the transmitter, an intermediate succession from a precoder is monitored by a detection circuit (40) to detect an appearance of each predetermined pattern and to give the intentional violation to the code succession. In the receiver a violation detector (30) detects both of the intentional and the unintentional violations in accordance with a detecting rule to produce a violation signal sequence (V n ). The two consecutive violation signals are distinguished from the violation signal sequence by another detector (55). As the predetermined patterns, two and twelve patterns are usable in a binary and a quaternary system, respectively.

Abstract: A control valve comprises a valve housing accommodating a valve spool which is axially slidable within a control sleeve to control the connection of a pneumatic supply line to an outlet leading to a pneumatic motor to thereby control the speed of the motor. In order to provide an improved motor response the area of the inlet supply connection (21) uncovered by the spool (35) is arranged such that initially only a small increase in speed is produced for a relatively long travel whilst subsequent movement of the spool produces a greater change in speed. In one embodiment two diamond shaped holes are employed for inlet supply connection port in the sleeve. In another embodiment a plurality of holes are employed and these are of different sizes and those of one size are offset relative to those of another size.

Abstract: An article having a flange is moulded between a mould core and a unitary mould cavity, the flange being formed during the process as a consequence of an undercut (37;49) existing in a first surface (15;51) of the cavity (14, 58). A ridge (39;59) is provided on a second surface (27;57) of the mould cavity adjacent the undercut (37;49). A fluid, i.e., air, is injected between the cavity and the moulded article (18;42) as the core (12;62) and cavity (14;58) separate in such a volume and at such a pressure as will maintain the article (18;42) in substantially complete and constant contact with the core as the core and article are withdrawn from the cavity. The flange (36;50) conforms to the cavity wall (15;51) until the article is free from the cabity, and subsequently the moulded article (18;42) is separated from the mould core.
